Different sized tires on original rims
by Chris K.
(Norfolk, Va)
Changing tires/rims?
I currently have P265/70R16 on my 2000 toyota 4runner which came with the vehicle. A friend of mine has a new set of P265/70R17's will they fit on my rims?
Editorial Comment:
Absolutely NOT!
Please don't even try to put a larger diameter tire on a smaller rim --in this case a 17 inch tire on a 16 inch rim.
No self-respecting tire professional would try because even the mounting of a larger tire on a smaller rim could be dangerous to the person doing the work. Even if it did work, you'd be running a serious risk that the tire would come off when it gets installed on the vehicle, or even worse at some time when it is travelling on the road.
There's a similar danger in mounting smaller diameter tires on larger rims, but the danger to the person doing the work is less because of the great difficult they would have in doing it.
Remember the last two numbers in the tire size is the rim diameter: P265/70R16 are 16 inch and P265/70R17 are 17 inch.
Just so there's no doubt about how I view this: Don't ever mount tires on rims which have a different diameter size!

Different sized tires on front and rear wheels
by Dennis
(Granite City, IL)
Different sized tires on front and back
A friend of mine can not afford new tires for his car. I am going to try and help him get some good used ones. I have found some I can afford, however he now has p225-60-R16 on his car, and the ones I found are p225-50-R16. Will this make a difference? I don't want to buy them for him if they will not work.
Editorial Comment: The situation you describe is not as extreme as you see in the lawnmower, but I've chosen this photo to illustrate that some vehicles are designed to operate with different sized tires (and wheels).
That being said, in the two tire sizes you mentioned, there is 22.5mm difference in the height of the tire sections, the 225/50 R16 being the lower of the two.
If you do mix tire sizes on a vehicle that was not designed for this, there could be some difference in handling, steering and performance because of the different wheel sizes, but the only way to really know if this is a critical difference would be to install the tires and do some test driving.
This might be more hassle, and even more costly and time consuming than just shopping around enough until you can put on tires which are the same size on all wheels.
If you're really wanting to help out your friend, would you feel comfortable in having him install tires which might cause him to have an accident because of the change in handling that he wasn't expecting, or prepared for, just to save a few bucks?

Tire Concerns: Best tire size for my car rims?
by Sohail
(Salmiya, Kuwait, State of Kuwait)
New Wheels
I just bought set of rims 16 inch for my BMW E30 325i with the follwing details:
Front rims: 16*7
Rear rims: 16*8
What is the best tire size for these rims? Please reply me back before i buy tires.
PS: The car has been lowerd.
It would be impossible to recommend an exact size for you but here are some things to keep in mind.
First. The tires should be designed to fit well on 7 or 8 inch wide rims. This may be the same sized tire, or you might wish to use a slightly wider tire on the rear because of the wider rim, providing the space in the wheel well will allow it.
Because your car has been lowered this may complicate the range of tires you could use since you likely have less room in the wheel wells.
I would encourage you to find a dealer who will try some tires on to see how they fit (and look) before you make a purchase.

Tire Concerns: Using 185/65 R15 tires in place of 195/65 15 tires
by Ben
(Lake Sunapee, NH, USA)
varied tire sizes
I have been given brand new 185/65 r15 tires but my car has 195/65 r15 on it now and I wonder if the new tires are ok to use.
Editorial Comment:
There are usually two issues to consider when you think about changing tire sizes, in a case like yours.
First is the wheel size. In your case both tires are designed for use on 15" wheels, as you can see from the sizes, so you are already on solid ground. Since the width of the tires (185 and 195) are only 10mm (or about 1/2 inch) different you're not likely to need a wider wheel, which could happen if you were thinking of changing from say a 195 tire to a 250 or something like that.
The second issue is the outside diameter of the tires as realted to the space in your vehicle's wheel well and clearance. In your case the small difference in the width and the same aspect ratio means that you have a minimal difference in the outside diameter of the different tire. The 185's are only 65% of 10mm smaller which is about 1/4 of an inch smaller than the original tires. This is not likely to create much of a difference.
So, in short -- go for it!

Tire Concerns: Tire width
by Rebecca
(USA)
Toyota
I have a 2008 Toyota Camry (standard) with a tire size of P215/60R16. Am I able to put P225/60R16 tires on this car? What effect will a wider tire have on the vehicle?
Editorial Comment:
It is very likely that you can use the 225 tire in place of the 215 with practically no notable effect on your vehicle, its performance or handling.
The new tire you're considering is less than 1/2" wider and only 1/4" higher than the original, but even with this little difference, it is a good idea to try-on the other tire and see if there is any problem in terms of space where the tire might rub or be obstructed by some part of the vehicle in the wheel well.
Also, it doesn't hurt to ask a couple of tire dealers if they've had any experiences with this larger tire. Who knows, what you might discover by asking around?
By the way, you might be interested in knowing that your car is also sold as the Daihatsu Altis in some countries. (Just a bit of car trivia, I felt like passing on.)

Tire concerns: Installing oversized rims on a Hyundai Elantra
by Cory
(NB)
Vehicle with oversized 40 inch rims
Can I put 16 inch rims on a 2004 Hyundai Elantra which has 15 inch rims as standard?
What you are thinking of may be covered in Plus Sizing which is the practice of changing the wheel size but maintaining the outside diameter of the tire.
The only obstacle you face in this case is to find a wheel where the bolt pattern matches the ones on your vehicle.
If you want to go beyond plus sizing, maybe even to the extreme in the picture above, then you need to start thinking about modifications to your vehicle to allow for the extra space which the new tires and rims are going to need.

Tire Concerns: What tire sizes can replace 30x9.50 r15 tires?
by Dena Forrester
(Jacksonville, Florida)
I have a 1998 Toyota 4 Runner.
4 new tires 2 years ago, the size 30x9.50 r15. One tire has nail in sidewall. Need new tire.
They are telling me that these tires are not sized right for my car and the replacement tire is no longer made by BF Goodrich in that size.
What do I do? Buy only one tire for $159 or buy 4.
Oh the spare is the old size - 225/75 r15. Great!
By the way, I bought these tires at Keith Pierson Toyota. Are they sized correctly for my car and are they safe to keep? Should I buy 2 and use one as spare? Please help.
Editorial Comment:
In theory the closest size to your original tire is 255/75 R15. A 265/75 R15 would likely work well too, but it would be a bit more than 1/2 inch larger in diameter than your 30x9.50 tire which is 30" in diameter and 9.5 inches wide.
Possibly the size you had is no longer made by BF Goodrich but you may find it made by another tire manufacturer.
Check on the door post on the drivers side or on the lid of your glove compartment door for a sticker from the manufacturer of the vehicle specifying what were the original tire size, if you have doubts about what is best for your vehicle.
You are much better off switching to another tire company rather than mixing tire sizes, especially on a 4WD vehicle.
If you've had no problems with the tires you now have, there's no logical reason to change to another size, providing you like the way they handle and look.
The smaller sized spare is of some concern. Your best bet would be to buy 2 tires and mount them on your car and use one of the older tires for the spare.
Depending on where on the sidewall your damage was, it might be possible to repair it and then to use that tire as your spare if it can be fixed, using it only for emergency use.

Tire and Wheel Compatability
by RR
(ID)
1995 Pontiac Firebird
People often ask questions like: " I have a 95 Firebird which uses 225/60 R16 tires. I'd like to put 225/55 R16 tires on the rear axle. What can I expect and will the tire fit on the 16" original aluminum wheel?"
In part, this is a subject that is covered in the article on Plus Sizing, even though there's no "plus" involved here. You're considering a Plus 0 change, and in reality are considering a tire just slightly smaller than what you started with.
The /55 or /60 is called the aspect ration and us use it as a percentage of the first number 225 to calculate the height of the tire's section, measured from the rim to the tread of the tire.
In this case, you're looking at lowering the height of the tire by about 11 millimeters from 135 to 123. This is less than 1/2 an inch, so the effect on your car's ride, performance, etc. is very likely to be almost nothing.
As for fitting on the original factory wheel, you're still using the same diamerter tire (R16) and the width of the tire is still the same (225) so unless the tire manufacturer recommends a different WIDTH of wheel from the one you have, you shouldn't have any problem. The chance of this is so low (based on the tires involved) that I wouldn't even bother to check, but if you really want to be sure, then get your tire dealer to check what size of wheel is recommended for this tire.
Since the Firebird is a 2 wheel drive vehicle, there's no problem in putting different sized tires on the rear axle, but this is NOT recommended if you have a 4X4 or all-wheel drive. Different sized tires, on these vehicles, can lead to serious problems.
Another article which might come in useful is the one on Sidewall markings which explains what you can learn from what is written on the tire's sidewall.

Plus sizing tires
by Krystle
(Texas)
Toyota Corolla LE --a candidate for Plus Sizing?
I own a 2004 Toyota Corolla LE.
I would like to put 17 inch wheels and tires on it. I have been doing research and I have found something called plus sizing. My question is if I put a 225/45 R17 tire on 17 x 7 inch wheels, would they work? I already have 15 inch wheels on 195/65 R15 inch tires.
I really would like to put a larger wheel to make my vehicle look better.
Krystle,
Plus Sizing seems to work for you.
In terms of outside diameter the switch seems to make sense and would cause no problems with speedometer accuracy or other issues.
One problem that might come up is with the width the the tire which might result in some difficulty depending on the space in your wheel wells. If you can arrange to try out a wheel and tire before committing to a purchase you can find out beforehand whether this would be an obstacle in your case.

Tire concerns: Using 225 55R/16 instead of 205 55R/16 tires
by Argie
(Canada)
"fat" tire
I bought 2 sets of 205 55R/16 tires (winters and V rated summer tires) for my a 2005 Lincoln LS
I have a 2005 Volvo S60 2.5T which comes loaded from the factory with 205 55R/16.
My question: since I would not use the Lincoln in the winter, could I safely replace the 205 55R/16 on my Volvo with the 225 55R/16 from my Lincoln ?
Any information that will help me understand a little more about tires sizes and its safe application.
Editorial Comment:
Unless you made a typo in describing your tire sizes, there are two issues at stake here:
First is the considerable extra width of the 225 tire over the 205 tire. There is a possibility that a wider tire might not work well in another vehicle because of lack of space in the wheel wells and possible rubbing when turns are made.
The other issue is the size, or width, of the rims on which the tires would be used. It is possible that the 225 tire might require a wider rim than you were using for the 205 tire. You'd be wise to check on the rim requirements that the tire maker has for that specific 225 tire and see if the rim on which you would use it is within the range which the tire was designed to fit.

205 or 215 R55 Which tire size represents more rubber?
by K.C
(Milwaukee, WI,U.S)
Typical tire size
I would like to know what these digits represent example 205 R55,215 R55, 225 R65.
KC, when you compare the numbers you've shown with the ones in the photo, you may note that you've left off some parts.
Let's start with your "205". It would be equivalent to the "245" in the tire size shown above. This is the width of the tire, measured in millimeters. Since 1 inch is 25.4 mm, the tire in the picture is just under 10" wide, a 205 would be about 8".
Following the first three digits is /70. This means 70% and if you multiply the first number, 245, by .7, you can calculate the height of the tire. This tire has a height of 171.5 mm.
To find out how much rubber a tire contains, you'd need to know the second number too because a short 255 tire might contain less rubber than a tall 205, but if the case were reversed and you had a short 205 wide tire, or even one which was the same width, the 255 tire would likely have more rubber in it.
The number after the width (R16) represents the size of the wheel rim. This also would influence the amount of rubber in a tire, because a tire on a 16 inch rim, for example, would have more than another tire which had a 15 inch rim.
Even if you had all the numbers, it still might be possible to exactly determine the tire size which contained the most rubber, because one tire might be manufactured using different components than another ... but with all the numbers, you could get an idea.
If you want more information about the information on a tire's sidewall (tire size, treadwear, DOT code, etc), see Tire Markings. which covers this.

Tire Concerns: changing tire size
by Gary Ledge
(Australia)
Currently, my tire size is 185/60R15 on steel wheels (rims)5.5j in size.
Is it ok if I change the tire into 195/55/R15 on the same set of rims? I have already calculated all the factors and the bottom line is. The 195 is .7mm smaller in diameter compare from the original tire size.
A change of this size should not produce any problems, but I always like to try on a new size before making a final decision to ensure that there are no issues. TG

Tire Concerns: Understanding Tire Sizes
by Mary
(Iowa)
Making sense of tire sizes
I do have 4- P65/65R17 tires and I found 4- P65/70R17 on sale my question is can I still replace my tires with these tires? I don't know if these tires will fit my rims properly or not since they have different numbers and I don't know what they mean.
Editorial Comment: You'll find a complete explanation of how to read a tire sidewall at
Tire Markings.
Briefly, though, the first number tells you the width of a tire in millimeters, the next number is a percentage to calculate the height of the tire section and the last number is the diameter of the rim, or wheel, on which the tire is to be used.
In the case you've given the the first number (P65) on both tires doesn't seem right ... it's likely P165, or possibly 265, but in any case, the second tire is just slightly higher than the first one, but the difference is less than 1/2 an inch, so you're not likely to face any problems switching from one to the other.

Effect of changing 16 inch tires for 17 inch Tires
by Greg
(Schaumburg IL)
My friend suggests that on her Chevy pickup her 16" tires were replaced with 17" tires on the same rims.
She pulls a 30 foot RV. She is wondering if this tire difference makes a difference in the truck's turning radius.
Recently, when backing the RV into a parking spot at a local campgound she had difficulty in doing the manouver which she had done previously without trouble. Having done this before she can't find any other reason for not "hitting the spot" dead on.
Can you shed light on this?

Up Sizing Tires
by John Z.
(PGH)
I am in the process of purchasing 4 all season radial tires for my 2005 Nissan Sentra. The tire which is on the car presently is a 195 55 r16. This tire is pretty expensive, I feel, for the type of driving I do plus it’s tough to get an all season radial at a descent price.
Upon reading and calling different places some places say I can “size up” With no problem but others say I shouldn’t.
The size they recommend is a 205 55 r16 which is more common and less expensive.
Is this a feasible solution or am I asking for trouble and if I buy this size will it effect anything on my car
Editorial Comment: What you're contemplating is known quite broadly as Plus Sizing and I recommend you read our article on it.
Specifically you're contemplating a Plus-Zero change, in which the diameter of the wheel does not change, but the width of the tire does.
The major precaution to take in this case is to ensure that there is no rubbing in the wheel-well produced by the wider wheel.
Generally, if you say within the bounds in the Plus-sizing system, you're not likely to find any issues which will affect the performance of your vehicle in a way that should worry you.

Tire Concerns: Changing Rim Size
by Jack
(Ottawa, Canada)
extreme tire!
I have an 09 Honda Accord EX-L with 225/55R17 stock tires. Can I change to 16" rims? I'd like to use my 16" alloys with 215/65R16 winter tires. What do you think?
Editorial Comment:
What you're thinking of doing is a kind of plus-sizing in reverse.
Instead of increasing your rim size you're wanting to decrease it, but the ideal situation is to keep the outside circumference of your new tire the same as what you started with so that there is no change in performance, speedometer reading or fuel consumption because of the change.
If you read the page I've linked to above and use the plus-sizing calculator that is available you need to work at it backwards to find the equivalent tire. In stead of putting in your existing tire, enter in the smaller rimmed tire size and do a plus 1 sizing, progressively changing the width of the tire until you see your original tire in one of the results boxes.
I've done this for you and the closest match for your 17 inch standard tire is a 210/65R16 tire, not the 215/65R16 you're considering which will result in a slightly larger diameter tire

Tire Concerns: Plus sizing wheels
I have a Camary with ugly 15 inch wheels and hub caps sized 205/65R15. I would like to replace them with 16 inch wheels tires such as 205/55R16. How would that work?
Editorial Comment:
You're thinking of doing what is commonly called Plus Sizing in the tire world.
Check out the link to get more details. In your case the closest theoretical sizes would be 220/55R16 or 200/60R16 to maintain the same outside diameter.
These sizes may not be available and you'll then have to choose something from what is available but with a slight change in diameter.
Try a 215/55 which is just slightly shorter or a 205/60 which will be just slightly taller, but either probably will be within a tolerance which would be acceptable.

Tire concerns: replacing P215/60R16 tire with P225/60r16
by JH
(Eaton, Ohio)
Ford Taurus
I currently have a 2003 Ford Taurus with factory rims. The tires which are worn out are p215/60r/16 and I am thinking of replacing those tires with P225/60R16 tires. Is this possible and what are the consequences?
Editorial Comment:
Changing from P215/60R16 tires with P225/60r16 tires is probably not a major issue.
To start with the difference in height of these two tires is just 6mm. (This is 60% --the aspect ratio of each-- of the difference in width which is 10mm). This means that the overall tire diameter will increase by 12mm and this works out to be about 1.4% of the original tire size.
This is the percentage difference you can expect in power, speedometer reading and fuel consumption...which isn't a great issue.
Aside from that unless you have been using rims which are not designed for 215/60R16 tires, this change will likely be within the specs for the existing rims, and the difference of having a tire which is 6mm higher than before is not likely to lead to a space problem inside the wheel well.
So, if this change is what you want ... go for it!

Tire Concerns: Variation from specified tire size
by Karen
(Raleigh)
sample tire sizes
My car is supposed to have 225/55/r16's as it does now, but I need to replace them and I was told I can put 225/60/r16's on there ...is this true?
Editorial Comment:
In theory there are several different alternatives which will work when you want to change to a different tire size on your car.
One approach is a concept called Plus Sizing in which the entire object is to maintain the exact same overall tire diameter even though you may increase (or decrease) the size of the wheel.
Another approach is to actually increase or decrease either the tire height or width within the constraints of the space available for the wheel and tire. In some cases there may be an effect on the power, performance, speed, fuel consumption, etc to consider ... in other cases the effect would be minimal.
In your case, it seems to me that the effects on car performance would be minimal, but in the tire sizes you mention you are considering a slightly larger tire which is about 11 mm (or about 1/2 inch) higher that the original.

Tire Concerns: Will a P225/60R16 Tire fit an 8" wide rim?
I have a rear wheel drive 1999 Pontiac Trans Am that I am driving in the winter. I want to mount studded snow tires on it that are P225/60R16. The Alloy rims are 8 inches wide, the snow tires are currently mounted on Ford rims that are 6.5 inches wide. The rest of the Trans Am tires are currently P235/55R16, car originally came with P245/50ZR16.
My concern is simply, will the narrower snow tire fit the 8" wide rim, or will it be too narrow to reach the bead sealing surface and "fall in" to the center of the rim?
Editorial Comment:
Industry standards say that a 225/60 tire should be used on a 6 1/2J, or 7J Rim.
Permitted rims are 6J. 7 1/2J and 8J
So it would seem that you are at the upper limit of the Permitted category.
Since I don't know your driving habits and road conditions I am reluctant to give you a strong OK, but if you are not going to be pushing your vehicle to it's peak performance and are carefully controlling your tire pressure, then I'd say you're not likely to experience any problems.
It is your responsibility to remember that you are pushing the limit with this choice.

Scooter Tire Sizing
by Tei
(Chicago, IL, USA)
1986 Volkswagen Scooter
How are Scooter Tires sized?
For example, if a 3.50-10 tire equals a 110/90-10 tire, then what is the equivalent of a 4.00-10 tire?
These are scooter tires for 50cc and larger scooters.
The short answer is that the equivalent to a 4.00-10 scooter tire is a 120/90 10 tire.
We're looking for more precise information, but for the moment we know the following:
4.00 is a measurement in inches, as is the 10, which is the wheel rim diameter.
In the other sizing method, if it is similar to car tires, the first number is a measurement in millimeters (probably the width) and the number with a slash (/90) is a percentage used to calculate the tire's height. The last number, is also in inches and is, the wheel diameter.

Tire Concerns: switch from 225/50 16 to 225/55 16 for increased clearance
by rollie antonio
(antioch, calif. usa)
Could I switch from 225/50 16 to 225/55 16 on the same rims for increased clearance?
With my current tires on 2003 Pontiac Grand Am GLT, there isn't enough ground clearance. The lower front splash guard rubs the the ground when backing up from driveway to the street. No modifications made, everything stock from the dealer.
Editorial Comment:
Probably for the amount you'd spend on changing tires to solve this problem, you might get better results spending the money on modifying your driveway so that there isn't such a sharp angle where it meets the street.
The change you propose would add about 1/2 inch height to your vehicle at the wheel ... it's not likely to help much.

Substituting 205/65 R15 tires for 215/65 R15
by Doug
(Canada)
typical Snow Tire
Is there any concern with using 4 spare P205/65R15 snow tires that I have to replace the worn out p215/65R15 summer tires on an older Dodge Caravan?
Doug, 
the switch means you'd be installing a tire which is slightly narrower (10mm) which is less than 1/2 inch, and a bit lower (65% of that), so --size wise it doesn't seem to be much of a problem for clearance. You may have to increase your tire pressure by an almost insignificant amount because of having a smaller tire, but really nothing to make much of an issue about (maybe 1/2 psi).
The biggest difference you may notice is the ride comfort and noise level, but if these don't bother you, go right ahead. Of course, I'm assuming the winter tires are in good shape, no sidewall cracking and even treadwear.

Tire Concerns: How does aspect ratio affect performance?
by Steve Riley
(Collingwood, Ontario Canada)
tire size showing aspect ratio
I have P215/65R15 all season tires on my 1998 Dodge Caravan.
I have a new set of P215/70R15 snow tires meaning the aspect ratio is slightly different. I think it is about 10 or 11 mm different.
Does that mean the tire is 20 - 22 mm taller ?
Will these still fit and what might I expect in terms of drive changes?
Editorial Comment:
You have the idea of the aspect ratio right, you multiply the ratio (which is the figure following the slash, and considered to be a percentage) by the first figure to calculate the height of the tire side wall.
Since there are two sidewalls you then need to double the result to determine the overall effect on the tire's diameter.
5% of 215 times two is 21.5 millimeters or just under 1 inch.
Usually a one-step change in Aspect Ratio (they always change in increments of 5), does not result in any significant change in vehicle performance, speedometer reading or fuel consumption. Yes, there is a change, but most people don't notice it because it is what they consider to be minimal.
A one step change in the ratio also does not usually cause any problems in terms of fitting within a vehicle's wheel well, however, if you have already been using tires which are not the standard size for your vehicle, you may experience some difficulty. In this case, I always recommend trying out the fit before committing to the purchase of a different size.

Tire Concerns: Effect of changing rim size
by arth
(philippines)
Will there be a significant difference if I change my rim and tire size for my 1st generation honda CRV which is currently 205/70/r15 to 215/65/r16 or 225/60/r16 or 235/60/r16. Which tire size could I use as the best replacement?
Editorial Comment:
What you`re considering is usually called Plus-sizing and you can find out all about it from Plus Sizing .
The basic aim of plus sizing is to maintain the same outside tire diameter so that you have no difference in performance or other issues.

Tire Concerns: Using smaller rims
by Stephen
(Texas)
I have a 2001 Ford Mustang with OEM 16 inch rims. The tires for this rim are much more expensive than if it had the 15 inch OEM rims on it. I found 15 inch rims on a 2001 Mustang in a salvage yard and everything seems to add up to me. However, is there some downside that I am not thinking about?
Editorial Comment:
What you are thinking of doing is rather common in the industry even though it may not be a wide spread thing.
To get more details on this you need to be looking at Plus Sizing but in reverse because instead of increasing your rim size you are going down.
As you astutely noticed, sometimes you can get tires which are considerably cheaper by changing a rim size, basically because the alternative tire size is probably more popular, more widely manufactured and more competitively priced.
If you do the Plus Sizing to a -1 (minus 1) your objective is to maintain the same tire diameter so you will have no performance changes or other issues. Just try to stay with a tire width which is fairly close to what you had on your original vehicle because if you don't you may have a problem with the space in your wheel well.
The likely "downside" is an aesthetic one ... some people don't like the looks of a higher profile tire which you will end up having to maintain the same tire diameter.

Tire Concerns: Low Profile Tires
by Robert
(Haralson County, GA)
Low profile tires
I've been having a hard time finding the right tire for me because most tire companies tell me different things. I need the know what is one of the best tires to buy if you need low profile tires because right now I don't have a clue. I need a tire to last as long as possible.
Editorial Comment:
I think almost all of us agree that we'd like to have our tires last as long as possible, but it could be difficult to agree on what is the best tire for everybody, low profile, or otherwise.
In principle, being low profile should not have any effect on the life span of a tire, but there are other things that generally go together with low profiles that may affect the tire life.
In many cases, most low profile tires are also high performance tires, made with special compounds which improve their traction and handling characteristics. These compounds generally have proven to be softer and less durable than those used on standard tires, and they wear out faster. That's part of the price one pays for demanding better performance.
The treadwear code on a tire sidewall may help in getting the longest lasting tire available -- the higher the number, the longer you can expect the tire to last. A tire rated at 500 should be twice as durable as one rated at 250, but be careful in comparing the rating between different brands. The comparison is most valid when applied to tires made by the same manufacturer, because they all do their own testing, so inter-company comparisons may not be accurate.
See our article on treadwear for more details.
Once you've identified one or two tires which you feel you'd be inclined to buy, try doing a web search on those specific tires to read what kind of comments people may have made about them, then make your choice based on your own experience, driving habits and expectations.

Tire Concerns: Smaller Tire on Back of car.
by EDT
(USA)
Different tire sizes?
My car tire size is currently P185/R65/14. I needed a new rear tire and so the mechanic shop replaced the one back tire with P185/R60/14. Will this affect my car in any way? If I have the shop replace it with the right size, would I be in need of an wheel alignment as well. Been driving like this for a week.
Editorial Comment:
The smaller tire under new conditions is a little less than 1/2" lower than the original tire in new condition.
If the other tires are considerably worn, this difference would be less and possibly almost not noticeable, especially if the pressure on the newer tire was increased a bit.
The increased pressure might compensate for the size difference but it would also make the new tire wear more rapidly.
The use of an odd sized tire should not cause an car which is properly aligned to require alignment, but it could result in handling difficulties and uneven wear.
For a short while, and depending on how much you drive, use of a slightly different sized tire shouldn't cause any mechanical problems, but the best course would be to put a properly sized tire on this wheel and --perhaps--keep this tire aa your spare, always with the idea of using it just in emergency situations until you have repair or replace a damaged tire.

Tire Concerns: Mounting R16 tires on R15 rims
by Harry
(Vermillion, SD 57069)
Audi A6 from 2008
Can I replace an R15 tire with an R16 tire on my Audi A6. A Walmart salesperson said it was OK. I just purchased a set of R16 Douglas tires at Walmart for half off (on clearance).
The sales person stated that although it is against company (Walmart) policy for him to mount the tires, the tires work perfectly well without any compromise to performance or safety. He recommended having another shop mount the tires.
Is this correct information?

Tire Concerns: Increased tire size
by Bob
(Idaho)
I have to replace all four tires on my vehicle. The size the car now has is 205/55R16. Could I put on 235/60R16 instead? What are the possible consequences of making this change to my car or its rims?
I will be driving on the same roads, under the same conditions and probably the same distances as before. Also, would there be any difference in tire life because of the change?

Tire Concerns: Effect of replacing P265/70/16 tires with P255/70/16
by Greg
(Gramercy, LA)
I have a 2005 Chevy Tahoe and it has P265/70/16 tires on it mounted on 8 inch wide rims and I am thinking about replacing them with a set of P255/70/16 Michelin Lattitude Touring tires as I can get a set of these at a savings of about 150 dollars.
The vehicle is strictly used on the highway and no towing is involved. What are the effects of such a change?
Editorial Comment:
The effects of this kind of change are minimal. Because you have a slightly smaller tire involved you may have to increase your inflation pressure slightly so as to not have your tires wear more on the shoulders than in the center of the tread.
Watch your wear patterns closely during the first couple of months to determine if you need to increase the pressure a bit. See wear problems for more details about this.
The new size is just slightly lower than the original and the vehicle will ride about 1/4" (7mm) lower, but since you're on highway this should be barely noticed, if at all.
Your speedometer will under-read slightly and your power transfer and fuel consumption will vary, but all of these will be minimal ... I'd guess you'd hardly notice it.
In the long run, however, the savings in tires will be probably be off set by a slight increase in your fuel consumption ... my calculations estimate that you'll have to use about 3% more fuel to cover the same mileage as your tires' life.

Tire Concerns: Using Larger Tire Sizes
by Ed

1999 Ford Taurus
My 1999 Ford Taurus has factory 15 inch mag wheels. The tires are 205/65r15. Can I use larger tires such as 215/65R15 or 225/65R15 tires?
Some models use 16 inch and even 17 inch wheels. There seems to be plenty of room for bigger tires.

Tire Size Upgrade
by Elliott
(California)
Mazda Protege
I have a 2003 Mazda Protege ES. OEM tire size is 195/50/16. Would like to upgrade to 205/50/16.
Can this be done without tires rubbing?
Is this size OK to safely install on vehicle?
Editorial Comment:
In theory there should be no problem with the change you propose. There is a difference in total diameter of the tires of only 9mm, which is slightly more than 1/2 inch.
Some cars have very little space in their wheel wells which could affect a change and result in some rubbing, and it is best to try a larger tire before making a commitment, but to start with it doesn't look like there should be a problem.

Tire Concerns: Power effect of down sizing tires
by joe rose
(georgtown ky.)
Ford F150
I have a 2006 F/150 Ford with a 4.2 engine and a 3.31 rear and need more power. Will changing 17 inch to 16 inch increase towing power?
Editorial Comment:
To get an answer to this question you need to calculate the difference in the overall circumference of the tires you plan to use.
If you follow the normal practice of changing the tire height to compensate for the difference in the rim diameter you will end up with no difference at all, so that you're wasting your time and energy in even trying.
If you stay with exactly the same size of tire except for the rim size, for example going from a 225/60R17 to a 225/60R16 you will end up with a tire which is 1/17th or about 5.8% smaller. This will convert in the equivalent increase in power, a decrease in speedometer accuracy and fuel consumption.
There is a catch, though, which you may want to take into account: You will have a corresponding lower amount of ground clearance because of this change, which may have some effects you don't want.
Also, there may be some negative effect in the sense that if you are wishing to use the extra power to tow or haul a heavier load, this may have other effects on your vehicle's overall capacity and could have effects on suspension and other systems that are beyond the design capabilities.

Tire Concerns: Comparison of 225/75R16 with 245/55R16 tires
by Bryant
(Maryland)
BFG M/T Tire
I came across an opportunity to get 4 very good M/T tires at a good price. The issue is the tires are BFG M/T 225/75R16 and my stock tires are 245/55R16. The vehicle in question is a 2002 Mercury Mountaineer.
I know I'll be going to a narrower tire but I want to know is it possible?
What are some of the side effects I might face in terms of Safety, Comfort and Noise?
Also will the aggressive tread pattern compensate for the narrower profile in anyway?
Editorial Comment:
A "quick and dirty" way to compare tires of the same rim diameter with another is to simply multiply the first two numbers in the size together. If the numbers are about the same, then the outside diameter is the same and no great difference need be expected.
In this case the new MT tire is somewhat larger than the original. The actual difference is 34mm which is slightly more than an inch and the overall diameter is increased by more than 2 1/2 inches.
The first concern, in this case is whether there is enough space in the vehicle wheel wells to operate without rubbing or bumping on anything. In the end, a test fitting should be tried if you have any doubts.
Because of the increased diameter and circumference the new tire will cause an error in the speedometer reading, there will be a slight change in power transfer and in fuel consumption.
If you run the new tire at the same pressure as the previous one, you may find that the ride seems harder and this may end up having an effect on your shock absorbers and suspension system over the long run.
Because of the larger tread lugs, you'll likely find this tire more noisy on paved roads, but you'll have better traction in mud, snow and other off-road situations.
There may not be any significant safety issues with the possible exception of the MT tire possibly being rated for a speed lower than the original tire. MT tires are not usually rated for the higher speed ranges.

Tire Concerns: the effect of changing tire size.
by Andrew
(Monteral, Canada)
My question is about changing tire size from original size P185R65-15 to P205R60-15. On Toyota Carolla CE 2004 (no abs). The tire will fit the ride will improve. At what expense? How will this change impact the speedometer, automatic transmission and the computers on the car?
Editorial Comment:
When you change a tire's size you need to multiply the tire width by it's aspect ratio (the second number) to get the sidewall height. Double this to figure the tire diameter when you add in the rim diameter.
In this case the difference between the first tire and the second one is just 6 mm. When you consider that the original tire diameter was 621mm, a 6 mm increase is less than 1%.
A one-percent change in tire diameter is not going to make a significant difference in power, speedometer reading or fuel consumption. If you never did the calculations, you might not even perceive the difference.

Tire Concerns: Alternate tire size for VW Passat
by Doug
(Johnstown, NY)
2004 VW Passat
I have a 2004 VW Passat. The car came equipped with P195 65R15 Michelin tires.
What should I consider if I wish to change tire sizes or brands for this vehicle?
Editorial Comment:
For any vehicle, the following may be considered.
- Usually the brand of tire that came as original equipment has little importance when replacing tires. The tire brand will have no effect on the performance or the warranty of the vehicle.
- Tires should be chosen with the road and driving conditions in mind, together with any personal preferences you might have for appearance. These may be different from what the manufacturer (or dealer) had in mind when the vehicle was sold new.
- To obtain the performance which the vehicle was designed to provide, the tire size should be the same as is recommended by the manufacturer. This is usually in a sticker posted on the driver's door or door post. This sticker will also provide the tire pressure which should be maintained.
- If you wish to change to a wider tire, which is shown in the first number of the tire size, reduce the aspect ratio (the second number) so that you get more or less the same number when you multiply the two numbers together. In the case of the 195/65R15, the closest match for a tire which has a width of 205 is the 205/60R15.
- If changing to a wider tire, it is a good idea to test fit the new tire to make certain that there will be no rubbing or obstruction because of the larger size inside the car's wheel well. Some vehicles, either by design or because of damage from an accident may have less space that could cause problems in using larger tires.
Rule of thumb: If you increase the width by 10, decrease the AR by 5. (This is because tire sizes are made in increments of 5, for both width and AR.)

Tire Concern: mounting a tire on a non-recommended rim
by Ramesh
(India)
Basic Tire Mounting
I wanted to mount 225/75R16 tire on 5.5J rim, but the tire manufacturer recommends a rim size range of 6"-7". What could happen if I mount this on 0.5" smaller rim width?
Editorial Comment:
By going outside of the manufacturer's recommended rim width, you are inviting problems for yourself and possibly others.
If the manufacturer gives a range, usually the ideal --or best-- fit is to use a rim which is exactly in the middle of the range, or 6.5 inches in this case.
What happens when you use a rim narrower than the recommended one? First, the bead of the tires are pinched together so you may have the rim actually riding on a part of the tire not designed to fit against the rim, providing possible extra tire wear, and stress because of the pressure against the tire.
You may have to increase your tire pressure to compensate for the lesser air volume in the tire which may further exacerbate the problem mentioned above and increase the possibility that the tire may slip off of the rim either because of the air pressure, or because of side pressures when the tire is subjected to lateral stress when cornering, etc.
If using non-protected mounting equipment such as that shown in the photo, you may be exposing the person who mounts the tire to an increased risk of accidental death or injury which can happen if a tire comes off during the bead-seating part of the mounting process.

Tire Size for a 2000 firebird
by Jarren Casstevens
(Middletown, Indiana, US)
Peter Biondo's 2000 Pontiac Firebird
I have a 2000 Firebird and I was wondering what is the largest size tire I could put on it. Right now they have 215s. What is the biggest I could go?
Editorial Comment: First, I think it is important to determine if you want to modify your car or not.
As you might guess in the photo above, that 2000 Firebird, seems to have tires much wider than the 215s which you mention. I would not be surprised if the rear wheelwells have been modified to accept those wider tires.
You did not mention the tire height which interests you, but unless you are prepared to make changes in your car, you are likely to be limited in this area too.
I hesitate to give you a specific tire dimension without seeing your vehicle in person. The best bet is to visit a tire shop and try tire and wheel combinations which appeal to you.

Tire concerns: Size difference of 215/65R17 and 225/50R17 tires
by jarod
(petersburg ny)
I have a set of Cooper snow tires 215/65r 17 and want to know if they will work on on my 2009 Accord The stock tires are 225/50R17.
Editorial Comment:
To determine the difference in size you need to compute the tires' height by multiplying the width by the aspect ratio.
The snow tires have a height of 139.75 mm (215 x 65%), and the stock tires have a height of 112.5 mm (225 x 50%). The difference is 27.25 mm which is over 1".
I'm not certain if the Honda Accord has enough space in all the wheel wells to allow more than an extra inch without rubbing or bumping when the larger tire is in use. If there seems to be lots of extra room when you look at your present tires, then you might want to test mount one tire in the area with the least amount of space to see if there is any problem.

Tire concerns: Tire Size Change

I have a Chrysler 300 2006 base model with stock wheels 215/60/18. I want to install aftermarket chrome rims 20x8.5 the tire size they recommend is 255/45/20 I want to get 295/40/20. Is that possible or How big can I go on this rim, I like as much tire as I can get.
Editorial Comment:
You may be pushing things a bit by going as far as you've described. I suggest you consult with someone who is in the business of selling wheels to determine the largest size that a specific wheel will support, since I don't have the specs at hand for 20" wheels. Those specs tell you what range of tires are acceptable for a given wheel.

Tire Concerns: Changing aspect ratio in tire sizes
by Tony
(st louis Mo.)
If my car uses 215/55r16 size tires on it and I found somebody with 4 new tires cheap, which are
size p215/65r16 can I put them on my car without any problems?
Editorial Comment:
Notice the second pair of numbers in each tire size. This is the aspect ratio, and in this case you're thinking of switching from an aspect ration of 55 to 65. This means you are going to be increasing the height of the tire sidewall by 10% so, multiply the width of 215 by 10% to learn that these new tires will be 21.5 mm higher than the originals.
Since 21.5 mm is almost one inch you need to see if there is enough space in your vehicle to all a tire which is more than 1 1/2 inches larger in diameter to function without bumping or rubbing in normal operation.
Some vehicles have lots of space, others are very tight ... the best thing to do is to test mount a new tire and try it out for size before making a purchase, just like you'd try on a pair of shoes.

Different size tires on the front and back.
by Joseph Godlewski
(Punxsutawney, Pa.)
Differing wheel size extreme
My wife has an 05 CLK Mercedes Benz conv't. The front tires are 225/45 R 17 91W. The rear tires are 245/40 R 17 91W. Michelin Pilot primacy, brand name.
We live in Penna and need all weather tires. Can we put all four the same size all weather tires on the car ?
Do you recommend any tire being better than another for our needs ?
Would appreciae any suggestions or recommendations concerning this issue.
Would the larger tire (245/40) work on the front of the car as well as the rear ?
Editorial Comment:
There's some interesting and valid concerns about different size tires expressed here.
One thing which causes confusion is determining the actual diameter of a tire. In this case we have the following tires:
225/45 R 17 91W and
245/40 R 17 91W
To determine the height of these tires, multiply the first number, which is the tire width in millimeters, by the number after the slash, which is a percentage. Applying this to the above numbers gives us:
101.25 mm and
98 mm
This tells me that the rear wheels are 3.25mm, or about 1/8 inch lower than the front. This is not a great difference, and could easily be erased by a difference in the wear-rate of the two wheels. (Or if one pair were older than the others.)
The only problem which might occur, if the same sized tire were used both front and rear, could be some rubbing in the front wheel well if there is very limited space and the wider tires (245) were in use. This could easily be determined by a trial fitting of the wider tire in the front, or avoid the problem completely by using the narrower tire all around.
If you're happy with Michelin I see no reason for you to change brands, but you should be aware that original equipment tires or another reliable brand won't make any difference in the performance or safety of your car. Most frequently the original equipment is decided by which tire manufacturer negotiates the best deal with the car maker -- nothing more.

Tire Concerns: Tube size
by Don

Lawn Mover Tire
What does 6.60-13.00 mean on mower tire? I need a tube.
Editorial Comment: Usually in mower tires, the first of the two numbers refers to the width of the tire and the second number is the size of the rim, in inches.
When ordering a tube you don't normally have to be greately concerned with the width, simply the diameter of the inside opening of the tube, so in this case you're looking for a 13 inch tube.

Tire Concerns: Difference between P265/60R18 and 265/60R18
by GT
(Florida)
I have a 2007 Toyota 4-Runner. The original equipment is P265/60R18. I want a smooth ride on the highway, plus we live in southwest Florida, warm to hot weather all year round. Does the "P" (Passenger)designation really make any difference in tire ride? Also, what variations in tire width or size would give me a smoother ride and still have a good grip in wet weather?
Editorial Comment:
I've never heard of any serious tire expert making a big issue about whether or not the "P" precedes a tire's size.
Some tire manufacturers use it consistently, others less so, and perhaps there are some that never use it.
If you find a tire that you like which has all the other characteristics to meet your needs, there's no need to give any further thought to having a "P" or not.
As for variations, my preference is to stick with what the car was designed to use unless you like to experiment or are planning to use the car in conditions which are extremely different from what it was made for.

Tire Concerns: Using higher tires on rear
by arturo
(emporia,ks, usa)
Mercury Cougar
I have 225/50R16 tires on my 1999 cougar and need to replace 2 but couldn't find that size. I've found 225/60R16 which is a little bit taller. Can I use them on the back side?
Editorial Comment:
By "back side" I'm assuming that you wish to mount these tires on the rear wheels.
As you note these tires are a bit higher than the previous ones ... 22.5 mm --which is slightly under one inch-- to be exact.
Provided there is enough space in the wheel well there should be no problem however this may have a small effect on your power output, gas mileage, and speedometer reading.
Personally I wouldn't worry about those differences, my biggest concern would be the space so that the tires do not rub or touch anything after they're mounted and in use.
Some vehicles have very little tolerance, so it's always wise to inspect them closely when changing to sizes not recommended by the manufacturer.

Tire Concerns: changing my tire size
by Trina
I have a 2006 Ford Five Hundred with original tire size of P215/60R17 and was wondering how would my car be affected if I switched the tire size to P225/55R17 or should I just stick to the original size?
Editorial Comment:
The tire you wish to use is a lower profile --55 instead of 60-- so it will be about 6mm lower than the original tire. Being a slightly wider tire you might have a slim chance of some rubbing ... check it out by trying a test fit first.

what does 6.0jx13 mean in reference to a tire?
by rohit
(kanpur, uttar pradesh, india)
what does 6.0jx13 mean in reference to a tire?
in a tire data I got this figure as rim size.
Editorial Comment:
You are absolutely right 6.0j x 13 describes the rim of a tire. 6.0 is the width of the rim while the 13 is the diameter of the tire which is supposed to be used on that rim. Both numbers are in inches. The "j" refers to the profile of the rim construction. This is the most common profile, but other profiles may exist, too.

Tire concerns: change tires and/or rims on Honda Accord
by Bob
(North Palm Beach,FL)
2008 Honda Accord
I bought a 2008 V6 Accord coupe that needs new tires- OEWM are far to expensive to replace with same- and I've found many affordable tires at a slightly different size. My original size tire is 235/45/18 - and I've found several great tires that are 225/45/18 -- WILL these be suitable replacements?
ALSO many locals are taking off their Acura or Honda 17" OEM setups and upgrading - could I use their 17" tire + rims on my car without hurting speedo etc?
Editorial Comment:
The alternative tires which you are considering would likely work with little to be concerned about since they are 4.5mm lower than the original tires. (235-225 x 45%=4.5).
The idea of changing the rims is not an unusual concept ... it's what is called Plus Sizing, but in reverse. I suppose you might call it Minus Sizing because what you want to do is lower the rim size by 1 inch. See our page on Plus Sizing to learn more about this. The idea is to choose tires which have higher sidewalls to make up for the loss of the diameter in the rim. Some people feel that this doesn't look as "sexy", but often the advantage is that you may be able to get tires which are lower cost if you choose one which is a popular and widely used size.
By carefully choosing the tire size, you may be able to maintain the exact same outside diameter of the tire so that there is absolutely no change in speedometer reading, power transfer and/or fuel consumption.
Good luck ... come back here and tell us what you finally did and the experience you've had.

Tire Concerns: 195/65/15 tires for 2003 Elantra
The 2003 Elantra calls for a 195/60/15, Was wondering if the 195/65/15 tire would fit?
Got a deal on these if they will fit!
Editorial Comment:
The difference in tire height between a 195/60 and 195/65 is only 5% (65-65), so the second tire is just under 10mm higher (less than 1/2 inch).
This does not seem like a substantial difference which should not make a great difference, but you never know for sure until you try them on the car. I have seen times where there was a problem because the car had experienced minor mechanical damage which was not known about, or properly repaired.

Tire Concerns: Will a 215/65 tire fit an a 1999 malibu
by Jennifer
(Manitoba)
I am currently switching to my winter tires, but all that I have on hand is a 215/65 R15 and I was just wondering if it would be all right for now, I have already put them on and they are just fine for driving but as soon as i turn right or left, they touch! Is this okay for now or is it a MAJOR problem?
Comment:
You have almost answered your own question. It is not normal for a tire to rub against some part of your car when it is operating.
If you are traveling slowly when this happens, you may not think it is important, but if it happens when you are travelling at a high speed the consequences could be disastrous.
Even if it only rubs, when you are turning and you do it at a low speed, you are causing extra wear on the tire and may even end up with that tire being worn out by doing this long before it is normal. In addition, you could be provoking some mechanical damage to your car, too, depending on exactly where the rubbing is taking place.
Please do not drive any more on these tires and switch to a more suitable size as soon as you can (like today)!

Tire Concerns: change of tyre size and rim size

I have a corolla of 2006 make with 185/70/14 and i would like to
change all 4 to 195/65/15, with this what will be effect on the
performance on the vehicle.
Comments:
Our Tire Size Calculator will show you the effects of swapping between these two sizes. Just enter your original size and the new tire size to see the exact differences.
Normally when you do Plus Sizing you want to choose the size to provide a tire which is almost identical to the original so that differences in speedometer and fuel consumption are minimized.

Tire Concerns: tire sizes for 2001 Ford Explorer
by dave
(tillamook or)
Stock tire is 235/70 16. I have some 225/60 16 studded snow tires. OK ro run this low profile tire on the Exlorer?
Comment: Check out our Tire Size Calculator to compare these sizes.
Except for the issues highlighted by the calculator, I don't think you'd have a lot of difficulty using these tires but they are beyond the 2% range which I consider to be the best fit for tire swaps.
Since the 225/60's are both lower and narrower you won't be faces with any issues because of rubbing or size constraints, but there still are other sizes that are more suitable for best performance of your vehicle.

Tire Concerns p205/60r16 in place of p205/65r16 tires
Can i put p205/60r16 in place of a p205/65r16 tires on a car
Ed Comment:
In general terms going to a lower profile tire on a car does not present the same degree of complication that going to a higher profile or a larger tire because you have no conflict over it fitting.
We made up a Tire Size Calculator which will help you see the effects of making a change from one tire size to another.
If you feel that you can accept the differences that this change will produce, just be certain that the new size you choose is the same load and speed rating as your OEM tire, this is the biggest safety issue. As long as this is kept in mind you should face no other complications that are apart from the differences that the calculator shows you.

Tire Concerns: 195/70R14 for VW Jetta 2002
by Lauren
(Seal Beach CA)
Before I switch 4 brand new tires from a now defunct 1996 Pontiac Sunfire to a 2002 Jetta with old tires I want to know if the difference in the 195/70/R14 from 195/65R15 is ok? I know it is not the original desired size but I have 4 new tires and hate to waste the investment if I can use them on the Jetta? Student in CA.
Check out the differences using our Tire Size Calculator and you'll see that while the 14" tire has a higher sidewall, it is actually a smaller tire in overall diameter. This, in itself isn't a big problem, but you will be spending more money on gas and will be travelling slower than your speedometer shows.
The big issue, however is the rims for the tires. I do not think it is likely that the rims from the Pontiac will fit the Jetta, although trying a test fitting may prove that they do. Whatever you do, you cannot mount a 14" tire on a rim which is 15" in diameter. If, somehow, you were to get the tires on the rims they would be unsafe to use because they are not seated properly.

Can I change from P225/60R16 to P215/60R16?
I have a 2001 Oldsmobile Intrigue that has always had the wider P225. I am thinking about using the P215 as I like the narrower tire for winter driving.
Is there any safety issues in going to the narrower tire?
Comment:
Use our Tire Size Calculator to see the differences in the two tires.
The difference isn't great and isn't likely to cause any major issues, especially from a safety point of view. If the narrower (and lower) tires don't concern you, they should be safe enough as long as the speed rating and load range is similar to what you currently use.

Tire Concerns: Sizing for Snows
by Frederic
(NC)
Snow tire sizing
We just bought a Mazda3. The base model comes with 195/65 R15 wheels/tires. The "touring" model we have has 205/50 R17 wheels/tires. I understand this to be "Plus 2" sizing, for ride and handling. Now for the tricky part ... I'm pretty sure I can put 195/65 R15 snows on a spare set of 15"rims, but can I get away with 205/65 R15 snows instead?
Editorial Comment:
The sizing you need can be calculated using our plus-sizing calculator. (See plus sizing page for a link to download it.)
210/60 R15 would be the ideal size if it is available, a 205/65 would be a slightly higher tire

Tire Concerns: Switch 205/65R16 with 225/60R16
by Jennifer
(Mississippi)
I have a 2003 Nissan Altima with 205/65R16's that I'm wanting to switch tires with a 2002 Chevy Monte Carlo that has 225/60R16's. Would this be an easy swap? The Nissan's tires are only 5 months old and I'm getting rid of it to keep the Monte Carlo and would like to keep my newer tires. Thanks for any help!
links
Editorial Comment:
At first glance this seems to be a rather workable switch since the 225/60 tires are only a small bit larger in diameter than the others.
The only possible draw back I see is with the tire width being 20 mm wider, which is almost one inch. Is there enough clearance in the wheel wells and when turning to accommodate this difference? If there is any doubt, do a test fitting to make sure. If you don't run into problems on this side it should work nicely for you.

Can I fit 215/60/16s on my Eagle Talon?
by Chad
(Canada)
I currently have 205/55/16s and wanted to know if this size difference is too much or if it could fit.
Editorial Comment:
When comparing two different tires the quick way to get an idea of fit is to simply multiply the first two numbers in the size together and compare this result to the same calculation with the other tire.
To get down to specifics, you need to divide the answers you got above by 100 ( just move the decimal point two places to the left) and you see that the second tire is 16.25 mm higher than the original.
In most vehicles adding just 16mm (just under 2/3 an inch) isn't going to cause much difficulty but because of possible variations which can be caused by body or mechanical damages, modifications and sometimes even normal wear and tear, I always will want to try a test fit before committing to a different size.

Tire concerns: width of tire
by Adrian
(Buffalo, NY, USA)
I have a 98 Camry XLE. Someone wants to sell me 18" rims with 245/Z40 tires on them. Can I put them on my vehicle and not have any problems?
Editorial Comment:
The question you've asked is really impossible to answer well because it's like asking if you'd look OK wearing a pink shirt without my knowing anything else about you other than that you're wearing Nike running shoes.
The important issue for you to determine if the diameter of the new tires on the new rims will be the same (or almost the same) as the tires you are now using, and whether or not the width of the tires is suitable for the space that your vehicle has to allow for turning without rubbing. This is, of course, assuming that your present tires are not causing any problems.
Our article on Plus Sizing may help you assess this issue.

Tire Concerns: CHANGE REAR TYRES FROM 185/70/R14 TO 195/65/R14
by SITESH GOSWAMY
(NAVIMUMBAI,MAHARASTRA,INDIA)
IN MY SWIFT DIESEL CAR ALL FOUR TIRES ARE 185/70/R14 I WANT TO CHANGE REAR TIRES TO 195/65/R14 FROM 185/70/R14
FOLLOWING ARE MY QUESTIONS.
1.WILL THE LARGER WIDTH REAR TYRE EFFECT SPEED
2.WILL LARGER REAR TIRES INCREASE/DECREASE DIESEL CONSUMPTION PER KILOMETER RUN
3.WILL LARGER REAR TIRES PUT UP INFERIOR/SUPERIOR OVERALL DRIVE QUALITY FROM PRESENT ALL FOUR EQUAL SIZE TIRES.
4.WITH LARGER WIDTH REAR TIRES THAN FRONT WILL VEHICLE STABILITY BE INFERIOR/SUPERIOR THAN PRESENT ALL FOUR EQUAL SIZE TIRES.
5.WILL THE SUSPENSION BE EFFECTED ADVERSELY BY LARGER SIZE REAR TIRES.
6.WILL SIZE 195/65/R14 TYRE RUB WITH REAR WHEEL WELL OF SWIFT DIESEL CAR
7.WHAT ARE NAMES OF MANUFACTURERS WHO MAKE 195/65/R14 TIRES.
Comments:
Several of your questions can be answered by using our Tire Size Calculator. Follow the link to try it!
In reality the 195/65 tires are smaller in diameter than the original tires but the difference is small. Performance may be affected in a small way, but not so much that you would notice it.
The extra width of 5mm on each side of the tire probably will not cause any problem in the wheel well, but a test fitting is always a good idea before making a purchase. I doubt if you would notice any difference in the comfort of the vehicle or have any suspension problems.
Most major tire companies would likely have this brand, but you need to discover if they are easy to obtain where you live.
The biggest concern when using two different sizes, for many, is what you are going to do for a spare tire. It is not a good idea to mix different tire sizes on the same axle, so you usually want to have 2 spares. But with a difference in size of only 5mm, this is not really a big issue.

Tire Concerns: 215/70R15 vs 235/70R15 how size change affects truck
by Chris
(Temecula CA)
2009 Toyota Tacoma Access Cab
I have an '09 Toyota Tacoma Access Cab--the smaller 4 cylinder model.
The one thing that I have always disliked about the looks of the truck is how small the tires look compared to the wheel wells.
It is now time to start thinking about new tires. I currently have 215 70 15 on the truck and was thinking of possibly getting some slightly larger tires.
I saw a similar truck that was running 235 70 15's and they filled the wheel wells better.
If I go with this larger tire how will it affect the handling of the truck. I drive about 45K a year on California highways.
My goals would be:
1. to fill the wheel wells
2. any better smoother ride
3. quieter ride
4. know any tires brand/models you can recommend.
Editorial Comment:
Let's examine your objectives one by one.
First, these tires will certainly be larger than those you already use. They will be 20mm wider and about 16mm higher. This does not look like it would cause any problems space-wise in your wheel well, but it is always best to try a test fitting first before committing to buying.
Your ride may be a bit softer because you will be using a lower tire pressure. You may or may not like the handling characteristics of a lower pressured tire, but there will be some difference, so don't be surprised.
Also, don't try to run the same pressure as your original tires, or you'll find that the center of the tread will wear down faster than the shoulders. Exactly what the difference in pressure will be is something you'll have to learn by experimenting and watching how your tires are wearing.
I suggest you start with about 2 psi lower. Monitor your tread wear for the first few months and lower it a bit more if the edges aren't being worn as quickly as the center of the tread. Increase the pressure if the wear is the other way round.
Once you find the best pressure, write it down and stick it under a plastic cover on your driver's door post, so you won't forget.
The quietness of the ride will depend to a great extent on the tread design you choose. If you pick a more aggressive tread that you had before, expect more noise. If you choose a similar design, there shouldn't be a great difference.
As for specific brands/designs I won't recommend any because it would be best to talk over your specific needs with a local dealer who would be in the best position to recommend what is most appropriate.
With larger tires on this vehicle you should expect a slight reduction in power, a slightly lower fuel consumption and a lower reading on your speedometer than you are actually traveling.

Tire Concerns: 17/8 rims on a 2002 Honda Civic
by Brian
(Calgary, alberta)
Can a 17/8 rim fit a honda civic 02 without altering my springs, and what size of tires can i use?
I imported advan racing wheels from the philippines and the size is 17/8", i don't have any tires yet cause im still researching on whether this rim size would fit my car a honda civic 02,my friend says it fits my civic but when i ask a tire shop about what size should i get for my rims they say that i better ask a honda dealership about it cause they dont have it on their chart? It made me think that i got the wrong set of rims
Comment.
Use our Tire Size Calculator to find a tire size for 17" rims that is within 2% of your original OEM tires and you'll not have to make any body changes. Enter the OEM tire size in the Current tire area and select 17 for the new tire's rim diameter.
That will take care of the tire size. Whether or not the rims will work depend on the bolt pattern your car uses and those on the rims. If they match, you're home free but if they don't then you need to find the ones which are made to fit on the car.

Tire Concern; Changing to smaller tire size
by Kevin
(Edmonton Alberta Canada)
I have a 2003 Chev Silverado
the tire on it now are 235-75 R 16
and I have a chance at free winter tires but the size is different
tires now are 235-75-R 16
like to replace with Goodyear Nordics
215-65-R 16 will this be ok?
Note: I do not carry any weight in the truck box at all.
Editorial Comment:
What is being considered here is the possibility of installing a smaller tire going from 235-75 R16 to 215-65-R16. Note, from the first number in each size that the second tire is narrower by 20mm (235-215) and also a lower aspect ratio (65 vs 75). These two factors combined result in the second tire being 36.5mm lower, which is roughly 1 1/2 inches.
As long as you don't need the clearance beneath the vehicle this change should not produce any significant problems.
Because the diameter of the new tire will be less than the original you can expect that you'll have more power delivered to the wheels, but your speedometer will under read because you are not advancing as much for each rotation of the wheel, and this too may affect your fuel consumption.

Comment
Check our Tire Size Calculator to see the difference, but the 215/60R16 is a smaller tire than the /70 tire.
It will certainly fit on the wheel and likely have no problem fitting on the car either, but it is the effects of using a smaller tire that you need to consider to see if they are worthwhile. The Calculator will tell you what those differences are.

Tire Concerns: 2006 malibu lt 215 60 16 to 225 60 16
I have 4 2000 impala steel wheels with 225 60 16 tires on them, will they fit on a 2006 malibu lt?
Comment:
Why don't you just try putting one of these on your car in the space that seems to have the least amount of room and see if there's any problem?
The 225/60 tire is just 10 mm wider (less than 1/2 inch and the extra height is just 60% of that difference, so there's not a lot of difference in either height or width between the two tires.
You'll soon see if there is any problem with the wheel bolts matching or not when you try on one .. if you have to force the wheel on to get in mounted, forget it because they won't fit, but I'd guess there's a good chance this won't be an issue.

Tire Concerns re changing P215/50/r17 fpr 205/50R17
by Jimmy
(Alaska)
I'm looking for snow tires. Does it make a difference if I put P215/50/r17 on a mazda3 with 205/50/r17?
Editorial Comment:
The tires you are considering are 10mm wider and 5mm higher (50% of 10). This difference does not seem like much, and may not be noticeable except in some vehicles where the existing tire is already a tight fit and there isn't enough space in the wheel wells.
Do a test fitting in the most restricted spot, check out the movement when you turn your steering wheel to the extremes and if you notice no problems, you're likely quite alright.

Change tires with different aspect ratio/size.
by anthony
(tucson,AZ)
Can I change front tires with WWW/65RDD to WWW/70RDD size? (Back tires still same size). Where: WWW=width, and DD=diameter
If the change of size applies to all four tires would it be more acceptable?
Editorial Comment:
Maybe this would be a bit more easy to understand if Aspect Ratio were called "Height". The number (65 or 70) in your example is, of course, not the height but it is a number which is used to calculate the height from the width. The AR is a percentage and the larger the number, the taller your tire will be. Exactly how much taller, will depend on the width you start with.
So, in your hypothetical example, increasing from a AR of 65 to an AR of 70 means you will be increasing the tire's height by 5%.
If you put the taller tires on the back you'll be raising the rear of the car up a tiny bit ... typically around 1/2 and inch for most passenger car tire sizes. Doing it all around of course raises the entire car.
The only other issue you might consider is the space in your wheel well. Very often a small change, like 5% of the tire's width won't make a significant difference, but sometimes you will end up with rubbing or other difficulties.
It's always a good idea to do a test fitting on the wheel where there seems to be the least room before switching all four wheels.

Tire Concerns: replace S60 215/55R16 tires with 205/65R16
by Alberto Barquin
(Queretaro, Mexico)
I have a Volvo S60 2004 and the tires specification is 215/55R16, my brother has a set of 4 new tires with a different specification (205/65R16) and I want to now if I can use them.
Editorial Comment:
A very quick and approximate way to tell is two tires are equivalent is to multiply the first two numbers in each size together and compare the results. Here you have 215 x 55 = 11825 and
205 x 65 = 13325.
Immediately we can see the second tire is higher because the product is bigger. Convert these numbers to measurements and we see that there is a difference of 15mm, or just a bit over 1/2 in the tire height.
The question is whether or not your Volvo has enough space in the wheel well to accept this much difference (which is really not very much). Do a test fit with one wheel in the one which has the least amount of space and you'll see.

Tire Concerns: Will 225/55R16s fit my 2011 Hyundai Elantra
My car 2011 Hyundai Elantra `presently has 205/55R16s on it. Will 225/55R16 fit?
Editorial Comment:
Here are the calculations relevant to your case:
Original tire
Sidewall: 4.44 in
Radius: 12.44 in
Diameter: 24.88 in
Circumf: 78.16 in
Revs/mile: 810.68
New Tire
Sidewall: 4.87 in
Radius: 12.87 in
Diameter: 25.74 in
Circumf: 80.88 in
Revs/mile: 783.41
Speedometer reading with new tire is 3.48% too slow.
When your speedometer is reading 60mph you are actually traveling 62.02mph
You may experience some problems with space in the wheel well due to a larger diameter, and you'd be wise to do a test fitting before committing to these tires.
A better fit for you vehicle would be 225/50R16 where there is only a sliver of difference in height and diameter.

Tire Concerns P215/65R17 for 2006 Equinox.
Can u put P215/65R17 Interstate Goodyear Tires on a 2006 Equinox.
Tires are on the front, Consumer Guide states specs Front Wheel material- P235/65R16. I am worried about the space between the top/side of tire and spring/shock.
Editorial Note:
We have created a Tire Size Calculator to help with questions like this.
Check out the calculator and you'll see that the 215/65 tire is smaller than the 235/65 tire so you're not likely to have any issues with a lack of space. There are other issues which the calculator will point out, but if you are thinking of only changing 2 of the 4 tires this is not usually a recommended practice, even on a vehicle that is not 4x4 … and certainly to be avoided on a 4X4 because of potential mechanical damage which this can provoke.
If you absolutely must change only 2 tires, make certain that you keep both tires on each axle the same size. This gets complicated if you have a flat tire sometime and are not carrying a spare tire of each size.

Tire Concerns: Plus 0 sizing on one axle only
by Andy
(Chicago Heights, IL)
I have a car with 205/65r16 tires, which I couldn't find at any retailers. The salesman sold me TWO 215/60r16 tires which he said I could rotate just fine. Is this true or not?
Editorial Comment:
This really isn't what Plus Sizing is about. In any kind of plus sizing the objective is to end up with a different width of tire that has the same diameter as before.
In your case you have had a tire installed that is just slightly smaller than the original -- 8/10th of an inch, so you are losing 4/10th of an inch in ground clearance. Your speedometer will read differently by about 3% and your fuel consumption will increase if you are putting them on the axle which drives the car.
Now, if you keep them both on the same axle, there should be no other problems unless your vehicle is 4WD. A mis-match of sizes on a 4WD car can result in serious mechanical damage but if it's not 4WD, then you should be OK.

I have 17inch rims for my 94 accord EX. I was told that for 17" rims I will need a tire size 205-45-17. My question is will a tire being 215-45-17 fit it without problems? Am looking for the chippest tire/rims to fit on my car and this is the only size I can find within my budget. I would appreciate any help.
Ed. Comments:
You are asking if it is OK to increase the tire width by 10mm (less than 1/2 inch) on the same rims.
Under most circumstances this would not likely cause any problems. The standards for most tires allow them to be used on a range of rim widths which are usually 1/2 inch smaller or larger than the recommended width in the rim. Since the tire width in your case is not changing by that much, there doesn't teem to be a problem.
Take note, however that the aspect ratio is staying the same, but because the tire height is calculated by using this AR there will be a change in the tire's height … here it will be 45% of the difference in width or 4.5 mm. That is less than 1/4 inch and is very unlikely to cause any problems.
Even so, use our Tire Size Calculatorto compare these two tires and see the effects of changing. I don't think you will find it excessive, but that's up to you to decide in the end.

Tire Concerns can a 99 corolla ve USE p175/75 r14
by Doug Richardson
(Bremerton, WA)
have a chance to place the p175/75 r14 studded tires on 1999 corolla ve?
Comment:
You've not provided us with the original tire size from your vehicle so it may be impossible to give you a precise answer.
According to my knowledge the 1999 Toyota Corolla came with two possible OEM tires 175/65R14 and 185/65R14, but it could be that yours is a different model and had a different size.
When you know that size, plug it in to the Tire Size Calculator and compare it to the 175/75R14 which you're wondering about and you'll see that it is a slightly larger tire (compared to the two sizes I've mentioned) and the effects of that increased tire size. If you have enough room and are prepared to accept the consequences, you can likely use this tire on your Corolla, but I'm waffling a bit now because I don't know what size to compare this tire with.

Tire Concerns: Will a 195 tyres fit a 7J rim?
by Keith
(Hampton, Middlesex. UK)
I have puchased a set of 15x7J rims with 205/60x15 tyres fitted to them. Unfortunately they are worn out but I do have a full set of newish 195/55x15 tyres already on my vehicle. Will these safely fit onto the 7J rim?
Editorial Comment:
According the the specifications I have available the 7" rims are the maximum that would be permitted for 195/55R15 tires.
It is good to check the rim width permitted for each tire size before making a switch, especially if you are using rims which are different from those originally installed in a vehicle. If you do, you can never follow the recommendations of the maker but have to be guided by the design characteristics of each tire in question.

will 225 60 r17 be ok on a 2002 sts cadillac?
by Doug
(Rapid City SD)
will 225 60 r17 be ok on a 2002 sts cadillac?
Comment:
I believe the OEM size for this vehicle was 235/55-17. I would use this size or your current tire size in our Tire Size Calculator to compare the differences. As long as you have the right wheels and stay within 2% of the original size you can generally make the switch without difficulty.

Tire Concerns; Sizing Up
by Ellie
(North Carolina)
I currently have a ScionXD that needs new tires, however not many places sell or carry the odd-ball 195/60R16 stock tires that the Scion comes with. Would a 215/55R16 be ok to use instead WITHOUT affecting anything major in performance or mileage? If not, what one size bigger CAN I use with the same stock rim in order to make my search for tires easier?
Comment:
Check our Tire Size Calculator to compare the two tires but I find your choice to be within the 2% range of size difference that is acceptable to me. You might also consider the 205/55R16 which is not quite as wide and could be less of a problem if the extra width causes problems with space in your wheel wells.

Tire Concerns: Larger Sizes
by michael faloon
(fair lawn nj)
i have a 2003 kia rio with 175/65r14 tires Will a 205/75r14 fit?
Comment:
See our Tire Size Calculator to learn the differences in these two tires.
The 205/75 is considerably larger and perhaps it may not even fit on the rim you have because it is also wider and may require a wider rim than the one which your original tire is using.
You are definitely getting into customizing your car if you switch to this tire, you may have to make some mechanical changes to have it fit, and unless you want to get into these things I would not recommend this swap.

Tire concerns: larger tires / rims on 2006 Kia Rio
Can i use 16 inch rims plus tyres 205/45HR/16 on kia rio 2006 whee the spec range is 195/50/15?
Comment:
Use out Tire Size Calculator
Tire Size Calculator to compare the tire sizes and if the new size is within 2% (the default setting on the Calculator). you should be OK for tires.
You also need to make sure you have wheels which fit your car, by matching the bolt pattern and the wheel offset. When these two conditions are met, you should be OK to use larger, lower profile tires.

mixing tire sizes
by Leslie Weeks
(Tulsa, Oklahoma, USA)
I have 3 p265 tires and one lt265 tire on my Tahoe. Three need to be aired to 35psi and the lt tire to 80psi. I had a flat and got a temporary one to replace the flat. Will this be bad for a few months?
Comment:
Something is definitely very wrong with your tire set up as you describe it. It seems to me that you may have been inflating the LT tire to the MAXIMUM pressure which is marked on the tire sidewall. The Maximum pressure is not the pressure which is normally used, and that tire, I would be almost certain, should carry the same pressure as the other tires.
You can usually find the recommended tire pressure on the Driver's side door pillar, or in the vehicle user's manual. Use these pressures and NEVER the maximum pressure on the tire except for very special and unusual situations.
You did not specify what the size was for the temporary tire which you acquired, but for best results it should be the same size, load and speed rating as your other tires. Otherwise, use it only to get to the nearest repair facility.

Tire Concerns: can i replace my original 14 inches rims to 16 inches rims for my 1998 hyundai elantra station wagon?
by soyti
(Scotland)
I have a 1998 Hyundai Elantra Station Wagon which has an original rims of 14 inches, front and rear. Then I bought a new rims and tires with a measurement of 215 60 R16. I would like to change my original rims and tire to R16.
Comment:
You are considering what is called: Plus Sizing and I'd recommend you read up on it to learn the basics.
Normally, there isn't much of an issue when you want to switch to larger rims so long as you adjust the tire size (the profile) to compensate. When a person wants to switch to smaller rims there is a possibility that there may not be sufficient clearance inside the rim to allow the brakes or other parts to function correctly.
Usually you want to end up with tires which have the same or very close to the same diameter as what your car originally came with and sometimes you may even see new cars being offered with optional rims which are larger. This, of course, is an indication that this kind of switch has already been tried and is suitable from the cars designers.

Tire Concerns: tire size
My 2010 Camry LE has 215/60/R16 standard tires. Can I use 235/60/R16 winter tires, or are they too wide.
Comment:
Whenever you want to compare two tires, it would be good to use our Tire Size Calculator o see the effects.
This will show you not only the size differences but the way those differences will affect the performance of your car, such as gas mileage and speedometer reading.
The 235 tire is not only wider by 20mm (which is almost an inch) but it will be taller by 60 percent of that difference because the aspect ratio of the two tires is 60.
So you will have a tire which is both wider and higher and this, of course may provoke a problem with space meaning that the tire could rub either constantly or only when turning or running over bumps. The best thing to do is to do a test fitting in the area that seems to have the least amount of space … usually the front wheel well, and if you are testing in that area then try turning the steering wheel from one extreme to the other and observing under the car if there is any obstruction.
If there is no obstruction, then you lower the car to the ground, and notice that there will be some settling which, again, will change the amount of clearance which is available because of the effect of the weight of the vehicle. If it looks close then you have to make a careful inspection before trying a road test.
On the other hand, if there is lots of room, then you may not have to do any further testing.
It is wise to try a test fit even if you know someone else who has used the same tire without problems. It is possible that your vehicle might have some mechanical difference that the other vehicle didn't have and this could be enough to make it impossible to use the tire.
I remember one client who had used a larger winter tire the previous year, and when he returned to swap the summer tires with the winter tires a second season discovered that the same tires were rubbing when he turned. When we looked further into the matter we discovered that he had had some mechanical work done on his steering or suspension (I can't remember which) but the effect was enough to make the larger tires rub in an area where they hadn't rubbed before.
Good Luck

Tire Concerns: Alternate sizes to 215/50 R17
by Edward
(Kitchener Ontario)
have tire sizes 215/50/17 low profile what other type can I install in my car
Got a Mazda Milenia but the tires are the low profile kind. I wonder what other tires sizes can be installed in my car instead, so I can have more choices. Size tires are 215/50/17 low profile for exemple If i want to go from low profile to a regular profile.
Ed Comment:
There are several sizes that would conceivably serve as alternatives to 215/50 R 17 tires and this is what our Tire Size Calculator was initial designed to show. Just enter your original tire into the top part of the calculator and 17 into the lower part while leaving the percentage difference at 2%.
The sises you see will provide approximately the same service as the original with little changes in performance or fuel consumption. You still need to be careful that any wider tire you might like to use will fit in the wheel well without any rubbing, especially when turning, but apart from that and making sure you choose a tire with the same speed and load rating (or greater) you're home free.
Remember, too, that you can click on any tire size that is calculated to get a more detailed comparison with your original tire.

Tire concerns:do 215/65R16 have same diameter as 225/65R17
by Neal
(Alberta)
I have a set of 215/65R16 winter tires and rims and I just bought a 2011 Equinox with 225/65R17 and was hoping the winter ones would fit.
Editorial Comment:
If your 215/65R16 tires are already mounted on rims, the only major concern about fitting is if the holes in the rims match up with the studs on the vehicle. If they match the rims and tires might work.
There will be a noticeable lowering in height because of the smaller rim diameter and the narrower tire with the same aspect ratio. If you can get by with a lesser degree of ground clearance, and realize that your speedometer will not read correctly, you can use these tires.

Tire Concerns: P245/70R16 106s vs 245/70R16 107s. tires
I have 3 P245/70R16 106s tires and replaced 1 with a 245/70R16 107s. Is there any cause for concern with the trade off. Had a nail in side wall and had to replace. Does the P in front of the numbers going to effect my vehicle.
Editorial Comment:
I'm not very good at mind reading, so I don't know if there is any cause for concern or not.
The P in front of the numbers is used by SOME tire companies to specify that the tires are made for use on Passenger Cars, but other companies don't do it. Since we don't know if your vehicle is a car or a light truck or a SUV, it is hard to say. Apart from that, the replacement tire is just rated for just a slightly higher load than the one it replaced and the speed rating is the same, so, in theory, there should be no cause for concern.
Whenever you ask questions it's good to give as much information as you can ... too much is better than too little. Tell us what kind of vehicle you are using, what driving conditions and kind of roads and anything else which might affect how and why you are using your tires. If you don't the answers you receive might not be the best for your situation.

Tire Concerns: Smaller Tire width
by Herbert Wilson
(Westminster, MD)
I currently have 265/75/15 on my light truck. Can I safely drop down to a 235/75/15? The width difference appears to be a little over 1 inch smaller.
Comment:
See our Tire Size Calculator to calculate the difference in the two sizes.
The radius of the tire is about 9/10th of an inch less which is usually much more significant than the tire's width when you are looking at a smaller tire.
Notice, in the calculator the speedometer differences and fuel consumption that this change will produce, if you are prepared to accept these differences, the size change would be workable even though it is outside the normal range which I like to recommend.
I do not see any safety issues in this change.

Tire Concerns: P205/70R15 tires for 2001 Oldsmobile Alero GL
by Mark
(Belgrade, MT)
Will a P205/70R15 tire fit on my 2001 Oldsmobile Alero GL? A friend has a set of Cooper P205/70R15 tires that are new that I can get very cheap. My car should have 215/60R15 tires on it. Will these tires work?
Comment:
To be entirely practical we seldom recommend that people switch to a different sized tire that is more than 2% different in diameter and the size your friend has is almost 5% larger. You may or may not have problems with clearance and will experience a drop in fuel efficiency along with an error in the speedometer reading.
With the way fuel prices have been going you may want to find another friend who has tires a bit closer to your own!

14" wheels on a 95 accord ex wagon?
by Charlie
(Cherry Hill, NJ)
Stock size is 195/60/15, I want to use 14" for snow tires. Will the wheels clear the brakes and work? I would use accord LX 14" wheels.
Comment:
Since other models of the Honda Accord from 1995 came with 14" wheels as OEM, there is a good chance that you could use the wheels and that they will fit without interfering with the brakes, however, the only way to know for sure is to try a test fitting with the wheels you now have and see if there is any problem that you can notice.
Use our Tire Size Calculator to choose a size of the snow tire that is within 2% of your original tire if you want to have the best results.

Tire Concerns: Installing 215/65R16 tires on a car that uses 215/55R16 tires
by Rick
(Lansing, NY)
Will 215 65 16 snow tires work on a car that uses 215 55 16 tires?
Editorial Comment:
This issues involved in increasing the aspect ratio (from 55 to 65) is that you are ending up with a higher tire ... in this case 10% (65-55) of the width, or 21.5 mm. This is nearly one inch.
The very first thing you need to determine is if you have enough space to allow that extra size to work and move freely without rubbing or bumping on any part of the car. This, is the most important consideration for a change of this magnitude.
Next you will end up with the car travelling slightly faster than what the speedometer shows, you will have less power transmitted to the wheels, and your gas mileage may improve by a small amount, compared with a tire of the orginal size.
For more information read about Plus Sizing which compares ways of changing wheel sizes to maintain outside diameter.

Tire Concerns: 215/60R16 snow tires vs 225/70R16
by Mike
(Syracuse)
I have two 215/60R16 snow tires from a station wagon I sold. Can I use these snows on the van I bought whose four original tires are 225/70R16?
If I can use these snows, can I use the two 215/60R16 snows on the front wheels and two of the 225/70R16s on the rear wheels? Or would I have to use four tires of the same size?
Comments:
If you will check our Tire Size Calculator to see the differences you'll see the snow tires are smaller than the other ones.
Regardless of tire size, you would always want to mount your snow tires on the drive axle of your vehicle for the traction they will provide, if you only have two.
As long as you do not have a 4WD drive vehicle, there is no safety or mechanical problem in mixing sizes but you do want to keep the same sizes on the same axle to avoid any stability or handling issues.
You likely will not have any problems with the smaller tires fitting but possibly, depending on your vehicle and driving conditions there could be some concern over clearance because of the lower tire.

Tire Concerns: will 225/60r17 work in place of 225/65r17?
by Greg
(Rockford,mi )
the 225/60r17 are snow tires. The 225/65r17 are stock tires.
The car is a front wheel drive 2005 Lexus RX330.
Comment
See our Tire Size Calculator to compare your tires and get the exact differences.
Usually if doesn't make a lot of difference if you are putting on tires which are slightly smaller than your original tires unless you have very limited ground clearance and you are concerned with bottoming-out in the areas where you drive. Obviously if you have an issue with scraping with your current tires, anything that gives you less clearance will only make the problem worse.
In your case you are losing only about 11mm of clearance which is not likely to be too much under normal driving but you are the best judge of whether this is a concern for you.

Tire Sizes for my 2008 Town & Country
by Warren
(Burlington, Ontario, Canada)
I'm looking for winter tires and the all season size on my van right now are 225/65R16's.
I have an opportunity to buy winter tires that are 215/65/R16's with rims. Is it ok to use the 215's instead of the 225's?
Also, two of the proposed winter tires say WS50 and the other two say WS60. Does this make a difference if I mix them?
Comment:
Check out these two tires using the Tire Size Calculator and you'll see the 215 tires are just slightly lower that the 225's. Unless ground clearance is a big concern for you this shouldn't be a problem.
It seems to me that you must be referring to Blizzak tires, since the WS50 and WS60 seem to be model numbers which Bridgestone uses. I'm not entirely familiar with the difference between these two so I can't guide you completely, but as long as you keep one pair on the same axle I don't think there would be any major issues in using two different types at the same time. I would put the ones with the most aggressive tread design on the drive wheels.

Tire Sizing
by M.Maldonado
(Oklahoma)
This may be a silly question, but i figure i'd ask anyways. I have a 99 mercury cougar and need to replace one of the tires.
The size on there now is 225/50/R16, a bit oversized i know, but they came with the car when i bought it. What i'd like to know is, can i use a 205/60/R16 tire on it instead of the factory 205/60/R15, because i have 16inch rims & not 15.
I also have the option of using 215/50/R16 but have found them to be a bit expensive. So, would it hurt to use a tire with an aspect ratio of 60 instead of the 50? what is the difference between the two? and would there be any differences in performance/handling?
Comment
See our Tire Size Calculator to find out the difference in the sizes. You can compare both your existing size and the original OEM size with any other size you wish in any rim size.
Generally when you increase the rim size you will decrease the Aspect Ratio so that the new diameter is about the same as what you started with. Normally, in Plus Sizing people try to stick with the same tire width (the first number in the size).
Whenever you increase the AR, you are making the tire higher and this sometimes results in not having enough space in the wheel well, along with other issues which the calculator will illustrate for you.
Normally I recommend that you stay within 2% of your original tire size to get the best results.

Tire Concerns: using 205/55R16 snow tire in place of 215/60R16 tire
What are the effects of using a 205/55R16 snow tires on a car which has 215/60R16 regular tires?
Editorial Comment:
The thing to note here is that because the aspect ratio is going from 60 to 55 on a tire of the narrower width, means that the "new" tire will be slightly lower than the original by 5%.
In most cases switching to a slightly lower tire will not be as likely to cause problems as much as a higher tire might, because you will not run the risk of bumping or rubbing because there isn't enough room.
The only issue that might come up is that of having less ground clearance, but even here, because there isn't that much of a difference in height, the loss is not likely to be noticeable unless, you have already found that you sometimes scrape the ground with the tires you normally use.
Gas mileage will be reduced slightly and your speedometer will show that you are going slightly faster than it would normally show by about 2-3%.

Tire Concerns: change 235/55 16 to 235/60 16
by Jeff
(Murfreesboro Tn.)
I have a 1997 s-10 2 wheel drive extended cab. I need new tires and it has a 235 55 r16 on it now. These are on factory rims and the tire size is hard to find. I was told at one tire place to change to a 60 instead of a 55. Can this be done without any problem, or will the tire rub?
Ed Comment:
Compare these two tires using Tire Size Calculator and you'll see that there is a very small difference between them and you're not likely to run into any difficulties in making the change.
The calculator may reveal other tire sizes that will be equally easy to obtain that would also be within an acceptable range that you can consider, too, but if you're getting a good deal on these ones you might as well go with them.

Tire concerns: Difference in tire size between a 40 and a 35??
I have a 02 Camaro SS and I am looking for tires. The problem I am having is the tires that came on the car are 285/40/zr17. I have a 17x9.5 rim. It is very hard to find a tire that fits that size, that is any good. Now my question, if I buy front tires at a size of 275/40/zr17 and the rear tires 315/35/zr17 would the sidewalls look funny and will the car set lower in the rear?
Editorial Comment:
If you calculate the tire sidewall height of each of these two tire sizes, you'll find that they are almost exactly the same. (315 x 0.35 and 285 x 0.4 both come out to apx 110 mm.)
So, the back will not be anywhere lower than the front and you'd not likely be able to notice any visual difference when looking at them.
The only possible problem might come from the mounting of the wider tire on your rims. I don't have the specs available for each of these tires, but supposing that the narrower tire is using the ideal rim, then it seems that the wider tire should be acceptable for that rim. The best bet is to ask your dealer to tell you what is the recommended and acceptable rim width for each of these tires.

Tire Concerns: car recommends 195/65/15 will 195/60/15 work
My 1999 VW Jetta recommends 195/65/15. Will 195/60/15 work?
Comment:
Plug in both of these tire sizes into our Tire Size Calculator and you'll see that the 195/60 is a bit smaller thant the 195/65 tire. The calculator will highlight the differences between the two.
Generally speaking there is not as much difficulty in considering a smaller tire using the same wheel on any car because there's no problem with space. You do lose some ground clearance but if you are driving in circumstances and roads where that is not an issue, then you don't have to worry about that.
In most cases a difference of no more than 2% will not bother most people and these are the best swaps to make when you do it. In any event, it is best to change all 5 tires (remember the spare) and avoid mixing two different sized tires on the same axle.

Editorial Comment:
Generally speaking the width range of tires that will fit on any specific rim depends on the tire manufacturer and the ideal rim for which a tire is designed.
It is possible that a tire made by one manufacturer of a certain size is designed to be used on a different sized rim that the same sized tire made by another, but usually sizes are quite standard.
In the case of tires which are 225 mm wide I am not aware of any tire which might be used on a 5 1/2J rim. According to the data I have recently checked the largest tire that is likely to fit on that rim could be a 215/80 R16. Any tire with a lower profile is going to require a wider rim.
